widths and thicknesses of said bands to suit the size of thewatch-holding frame or {case and the arm of the wearer, and with dueregard to symmetry or '-l1armony inthe use of the wrist-watch product. II I The details of structure of the improve ment will be fullyhereinafter described in connection with the accompanying sheet ofdrawings, in 'which latter Figure 1 is a plan view of thewrist-watch andits attaching band or'strap, showing my improved mounting-connectionwith a medium width of strap; Fig. 2, a side elevation of the completestructure; 3, afragmentary plan, partly in section, showing the-improvedmounting-connectionv herein; Fig. 4, a detail section of themounting-connection, taken on the dotted line i, 4-, of Figs. Qand 3; 5,a perspectiveof one of the sleeves forming a part of the saidmounting-connection, such sleeve in this view having a nar row slot fora thin band or strap; Fig. 6, a

, plan of the strip. of sheet metal used in forming the sleeve seen inFig. 5; Fig. 7, aperspective similar to Fig. sleeve v. th a wide slotfor a heavier or thicker band or strap; and Fig. 8, a plan of the stripof sheet-metal used in forming the sleeve seen in Fig. 7.

In these views of the drawings, A indicates the usual watch-holdingframe adapted tocontain the encased dialed movement or watch-proper I)and having spaced lugsQ. C, at its opposite ends for the hinged orpliable reception of the opposite ends of the wrist ban d or strap I). fi

T he wristband, in use, made in different widths and of differentthicknesses of mate-' rial, and it is desirable that the hinged connedtion or coupling member between the said opposite ends of it bethicknesses and widths- To snchend nay-in '9 is formed from a fiatrectangular st 5, but showing the constituted so as to'prop erly conformto or well meet its sald varying 1927. Serial No. 190,024.

tl'iei'efore, is composed of a short lengtho-f tubing 9 that forms asleeve to fit freely, but not loosely,between each of the pairs ofextend d. lugs C, C, at the opposite ends of the z 3 iding frame A. Eachofthe sleeves rip of sheet1netal or blank, as shown at a; and b,*in

Figs. 6 and 8, respectively, the strip a, in

Fig. 6, having at one end thereof an'elongated notch'or cut-out,shouldered portion 0;, and

the strip 0, in Fig. 8, having at-both ends.

thereof similar notches I). In forming the tubing; from these strips thestrip a, of Fig.

'6, is used to produce theslceve of Fig. 5, to

accommodate the eye'or loop 10 at each end of the wrist-band D that isslipped into place" within the sleeve, (which latter is of spring orresilient metal), by opening the slit-b.6- tween the opposite adjacentends of the elasv tically closed strip a. When the said eye has reachedthe position of the notch a, so as to fully register therewith,itbecomesautomatically seated or snaps into its proper place in the sleeveftheshouldered ends ofthe notch preventingits endwise movement or displaceient from the sleeve until required to do So .a-nc. accomplished byspreading open the said sprin -closed meeting ends of the tubingstrip a.In order to meet the varying widths of wrist-bands the sleeves 9 are allmade to fit freely, as above stated, between the pairs of lugsC, G, on,thewatch-holding frame, but the len 'th of notches a is made to vary,

a longer notch to suit the Wide band "and the shorter notch'to SLUt' thenarrow band,

all to suit the varied conditions connected with the individual tasteand the size of the arm or wrist of the wearer. practice, however, ithas been found necessary to allow for but about threewidths of bands,viz: abroad, a medium, and anarrow In actual f hand, and sleeves withcorresponding lengths of notchesce-to suit'the width of band. areselected for the demands of the tradeh Tofur: ther provide for thickerbands I notch uthe strip bat its opposite ends,as above stated, and,when the said opposite ends are brought together under the tensionof-tho spring metal thereof, the notches Z)" duly register to form abroader slot or opening forthe accommodation of the thicker orheaviermetalfof the eye orloop 10 atthe opposite ends of'the said'band.The-adjustment or change from a broad to a narrowband, or the reverse,can be readily made by the sub; stitution of sleeves havmg'long'mediiim,

short notches of bands.

A tubular connecting axle or pintle 11, havinig to suit such dilferentwidths b ends 12, 12, is provided Within each of the said sleeves 9 and,coincidentally, Within the endloops 10, 10, of the band, to flexiblyconnect the latter With the opposite lugged ends of the Watch-holdingframe A. V The said bearingends 12 oi the pintle 11 engage minuteopenings 13 in the lugs C and suchpin tle, being hollow, is therebyadapted to acconriodate the said bearing-eni'ls in aresiliently-cxtcnded manner by the additional use of an internal spiralspring lei, as best seen in Fig. 3. A short tubular fillenplug l5 isinserted, with a drive-fit, in each endof said hollow pintle ll toprevent any undue movement oilsaid bearing-ends. Thus, the said pintlecan'bo conveniently placed between the lu With its spring-extendedbearing-ends in the openings a 18 for the free flexible connection (Ifthe opposite loop-ends 01"- the Wrist-band therein.

The bearing-ends can be easily displaced by simply inserting a pointedinstrument in either opening 13 and compressing either 01 saidbearing-ends until it clearsthe inner face of the adjacent lug. Thecompression of either ofthe little spring-extended spindles 12 willpermit themain spindle or pintle 11 to be inserted or ithdrawn to andfrom place between the said pairs of lugs C, C, for

' the attachment or detachment, as'the case-may be, of the encasedtinie-piece between the opposite ends ofthe rist-band. Intermediate thesaid. opposite ends of the Wristband is reduced, internally-headedbearin a provided a suitable clasp E to connect, in adjusted position onthe Wrist. the customary pair of arc-shaped members that form the saidWrist-band.

The opposite ends of the sleeves 9 are prel erably, but notessentially,inwardly flared, as best seen in Fig. 3, to cover or inclosethe gap over the ends of the eyes or loops 10 and impart the-desiredWorlnnanlike and aesthetic effect or finish to the device for use.

It is intended that the miproved mounting herein is adapted for similarexpansiblely encompassing said tubular'pintle, and alongitudinally-split elastically closed auxilpassing the said tubularpintle and loop formation between thelugs and having a longitudinal slotadapted to accommodate the width of the Wrist band free from cross-Wiseshifting of the mounting.

In testimony whereof I hereunto affix my signature. i
